Specification of Letters Patent.

' Patented July 16,1907.

Application filed gust 18,1906. Serial Ila-331,142.

Be it known that I, BRUCE WORTHINGTON, a citizen of the United States,residing at ,Winchester, in the county of Frederick and State ofVirginia, have invented certain new and useful Improvements inWindow-Screens, of which the following is a specification.

This invention relates to new and useful improvements in window screens,and more particularly a screenadapted to be placed within the windowframe above or below the sash, and to be so connected with the sash asto automatically span-the space between the bottom of top of the sash asthe case may be, and

, the window frame, as the sash is raised or lowered.

The invention contemplates the provision of an extremely simple holderin the way of a strip having connected thereto at opposite ends tworesilient end pieces provided with sockets for the reception of theshaft of the spring-roller around which a screen is rolled very much inthe same manner as in the ordinary curtain or shade, a strip adapted tobe attached to the sash, and means for firmly holding the strip androller in place in the sash below theframe. v

The object oftheinvention is to provide a device of this character thatcan be readily put into place in the window frame and readily attachedin operative position to the sash, and to provide a construction wherebythe-roller maybe readilyinserted in the holder and removed therefrom,and to provide such construction of theend pieces as to permit them tofit snugly against the flattened surfaces ofthe window sash, and at thesame time not interfere in any way with the easy rotation of thescreenroller when mounted in the holder.

A further object is to provide a convenient means, in the way of arotatable rod for guiding the screen and keeping the same smooththroughout its movements.

In the drawings illustrating the invention: Figure 1 isa perspectiveview of'the window frame showing my improved device attached thereto.Fig. 2 is a perspective viewof the holder with the spring rollerremoved. Fig. 3, is a section of aportion of the window frame, taken alittle above a holder in place, showing the manner in which the endpieces engage the sides of the frame, and the manner in which thecam-devices hold the holder, in place in the window frame. In this viewthe stripwhich is connected with the window sash is removed forclearness of illustration.

Fig. 4, is a perspective view of the strip adapted to be attached to thewindow sash. Fig. 5, is a vertical section of one of the resilient endplates, showing the formation thereof which adapts it to receive theends of the roller-shaft, in such manner as to'permit the easy rotationof the shaft when the holder is in place in the window frame. Fig. 6, isa perspective view of a cam-device which I employ to secure the holderin place in the window sash. Fig. 7, is'a longitudinal section throughthis device.

Referring to the drawings: The numeral 1 designates a strip preferablyof wood. In carrying out my invention I rabbet this strip at oppositeends as indicated at 2, for the reception of oneside 3, of the resilientend pieces 4, which end pieces in addition to the part 3compriseresilient portions 5,'at right angles to the pieces 3. Each piece 5 isprovided with a cen-.

tral concave-convex depression'G, one of which is provided with asquared opening 7, for the reception of the flattened end of the rollershaft, and the-other is provided with a round opening 8, for thereception of the round end of the shaft. These ends are resilient, thatis to say they are formedof metal possessing the property of returningto their normal position after having been sprung in one way or theother. By the use of the resilient ends, Iv am enabled to readily removeand insert the roller, thus avoiding the necessity of supplying a newholder should the roller get out of order, and for the purpose ofremoving the roller to tension the spring therein when this becomesnecessary.

Close to the peripheral edge of the strip 1, I arrange a rod 9 which isformed with'ends 10 of smaller diameter than the rest of the rod, andthese reduced portions pass into and turn in apertures 11, made in thepieces 5, and have such play therein as not to provide a lock that wouldinterfere with the resiliency of the end pieces.

The numeral 12 designates a spring-roller of ordinary construction,having a shaft provided with a flattened end and a round end. Thisroller has a screen thereon preferably formed of linen mesh or someother strong flexible material, which when the screen is in place in theholder, passes between the edge of the strip 1, and the rod 9.

The numeral 13 designates the strip adapted to be attached to the bottomof the window sash. This is provided with a longitudinal groove 14 forthe reception of a tongue 15, which fits into the groove upon the edgeof the screen. The tongue is held in place by brads or other meansadapted to firmly hold it in place upon the screen. The cam-devices forsecuring the holder firmly in place in the window frame are of specialconstruction and will be described in detail.

The numeral 16 designates a plate formed with a central depression orguide-way 17, in which slides a plate 18 provided at-its outer end withspurs or teeth 19. The plate 16 is slotted as indicated at 20 and a stud21 is mounted upon the plate 18, and extends through this slot Where itis connected with a cam 22, so shaped that when the plate 18 iswithdrawn, its edge will abut against an ear 23 integral with the plate16. The plate 16 is further formed with flanges 24 by which it may beconveniently attached to the face of the strip 1, and is also providedwith downturned ears I 25 which embrace the ends of the strip 1. The cam22 has formed thereon a laterally extending thumb piece by which it maybe conveniently gripped and manipulated to cause the spurs to beinserted in the window frame. To withdraw the teeth of the plate 18 itis only necessary to rock the cam forward and push the same togetherwith the plate 18 toward the opposite end of the strip 1, as it will henoted that the cam and the plate upon which it is mounted, movetogether.

In operation the strip is placed in the window frame below the sash,with the resilient ends of the holder fiush against the sides of thesash between the guiding strips (1 of the frame. This, as shown in Fig.3, will bring the cam-devices in position to have the teeth on the plate18 engage the guiding strip of the sash. The holder is locked firmly inplace by the manipulation of the cams, when the strip 13 is secured tothe lower edge of the sash. As a means for securing this strip Ipreferably provide hooks b which engage pins or buttons c upon the sash.When this connection is made the window sash is raised or lowered to anydesired height, when it is obvious the screen will span the spacebetween the holder and the sash.

While I have shown a cam-device mounted on each end of the strip, 1 donot desire to be understood as limiting myself to this arrangement, asobviously one end of the strip may be provided with spurs which arepressed into the sash, and the other end provided with the cam, nor do Idesire to be understood as limiting myself to the use of two resilientends of the holder, as it is obvious that the purposes of my inventionwould be accomplished if one end were stationary and the othersufficiently resilient to permit of the required movement of the end toremove and insert the rollershaft.
